The RCBS Cowboy Roll Crimp 3-Die Set is made from high-quality materials, and they have been heat treated to offer an authentic appearance. This set was specifically designed for use in reloading straight-walled ammunition, like the type used for period firearms for Cowboy Action Shooting.

Included in the RCBS Cowboy Roll Crimp 3-Die Set are three dies that have been optimized for use with lead bullets. These dies have also been built to different dimensions than standard RCBS dies to allow for proper sizing, expansion, seating, and crimping.
